Gang electric - KYN28A - 12 in the cupboard

Product overview
This device for indoor metal armoured withdrawable switchgear (hereinafter referred to as the switchgear), department of 3-12 kv three-phase ac 50 l - z single busbar and complete sets of power distribution device of single bus section system.
Mainly used in power plant, small and medium-sized generator power, industrial and mining enterprises and power distribution and electric power system secondary substations of electric power and large high voltage motor starting, etc.Implement control protection, monitoring, the switchgear meet DL/T404-91, IEC298, GB3906 standard requirements, prevent the loading of push-pull circuit breaker handcart, prevent or circuit breaker, to prevent the earthing switch is in the closed position close circuit breaker: prevent straying into charged compartment, prevent the charged, "miss grounding switch function of the chain, as well as with VS1 vacuum circuit breaker, can also be used with ABB vD4 vacuum circuit breaker, can also with domestic ZNl 63 ZZNL 28 series vacuum circuit breaker, it is a superior performance of the power distribution device.
